Bespoke Gas Mixture for PBF-LB
Optimizing Process Reliability and Productivity with ADDvance Laser230
Developed for Consistent Results
Many variables affect the quality of the final part in PBF-LB printing. These include the melting behavior of the powder, which can also impact the speed at which the part is produced and the resulting fumes and by-products. Fumes, metal vapors and spatter, for instance, can compromise reproducibility by disturbing the laser beam. A disturbed laser beam will not provide the energy required to reliably join the powder particles, increasing the risk of print defects. In addition, by-products like vapor condensation and spatter can deposit on the surface of parts printed in close proximity and increase the need for post-processing.
Argon can help contain this surface redeposition process. The ADDvance Laser230 process gas combines argon with helium to take PBF-LB dependability and reproducibility to the next level. It reduces particle redeposition and porosity and the resulting rework efforts, also mitigating fume formation and accelerating cycle times. It is ideal for additive manufacturing of lattice structures made from titanium, nickel, copper and aluminum alloys (such as Ti64, alloy 718 and AlSi10Mg).
Highlights of our ADDvance Laser230 Process Gas Offering

- Cu components printed with improved density and reduced porosity defect size, complying with aerospace requirements even at higher productivity rates
- Reduced particle redeposition for fewer internal defects and lower risk of interference across high-quality parts printed in proximity
- Less post-processing effort due to smoother surfaces
- Ease of part qualification
- Less fume formation and laser disturbance for greater reproducibility (e.g. 70% less porosity on Ti64 lattice structures)
- Accelerated print times (with up to 10% rise in productivity on Ti64 lattice structures)
- One-stop service with plug-and-play deployment
- Works with all standard 3D printers
- Special productivity parameters available on demand
- Flexible choice of gas supply modes with pre-mixing or on-site mixing options
- Even greater protection against contamination risks for higher reusability in combination with ADDvance O2 precision atmosphere control
